Warranty: 1 YEARS ,Part name: Combination instrument assembly C3801050-C5302
This Combination Instrument Assembly (Part No. C3801050-C5302) is exclusively engineered for Dongfeng VR truck models, developed via 3D laser scanning of the original vehicle’s dashboard instrument cavity, wiring harness interface, and steering column alignment marks. It adheres to strict OEM dimensional tolerances: overall size (280mm×160mm×80mm), mounting hole spacing (180mm center-to-center for dashboard attachment), 16-pin connector pinout (matching the VR’s 24V CAN bus electrical system), and viewing angle alignment (15° tilt to match the driver’s natural line of sight). Unlike universal instrument clusters that require dashboard modification or adapter harnesses, it directly snaps into the pre-existing instrument cavity and plugs into the original wiring harness—no rewiring or drilling needed. This precise fit eliminates gaps that cause rattling, avoids interference with steering wheel movement, and ensures seamless communication with the truck’s ECU (Engine Control Unit) for accurate data transmission

PRODUCT DESCRIPTION
Multi-Functional Data Display for Comprehensive Vehicle Monitoring
Designed as the central information hub for the Dongfeng VR, the instrument assembly integrates a full suite of monitoring functions to keep drivers informed of vehicle status. It features a 4.3-inch LCD screen (480×272 resolution) that displays real-time data: engine speed (0–3,000 RPM), vehicle speed (0–120 km/h), fuel level (0–100%), coolant temperature (40–120°C), oil pressure (0–10 bar), and battery voltage (20–30V). Additionally, it includes warning indicators for critical issues (e.g., low oil pressure, high coolant temperature, brake system faults) with audible alerts (85dB) to ensure timely driver response. The LCD screen also supports trip data tracking (distance, average fuel consumption, driving time) and maintenance reminders (e.g., oil change, filter replacement) based on mileage. Unlike basic instrument clusters with limited metrics, this multi-functional design provides complete visibility into vehicle performance, reducing the risk of breakdowns
High-Visibility Design for Daytime & Nighttime Use
Engineered to ensure clear readability in all lighting conditions, the instrument assembly uses advanced display technologies and optical optimization. The LCD screen is equipped with a high-brightness backlight (500 nits) that automatically adjusts based on ambient light (via a built-in photosensor)—reducing glare in direct sunlight and dimming to 150 nits for nighttime driving to prevent eye strain. The analog-style gauge markers (engine speed, speedometer) are coated with a phosphor material that retains light for 5 seconds, ensuring visibility during sudden light transitions (e.g., entering a tunnel). The screen’s surface has an anti-reflective coating (AR coating) that reduces light reflection by 70% compared to uncoated screens, maintaining clarity even in bright daylight. Unlike low-visibility instruments that force drivers to look away from the road, this design ensures data is readable at a glance, enhancing driving safety
Durable Construction for Long-Term Reliability in Harsh Environments
Built to withstand the harsh conditions of truck cabins (vibration, temperature fluctuations, dust), the instrument assembly uses robust materials and structural design. The outer casing is made of impact-resistant ABS plastic (UL94 V-0 flame-retardant rating) that tolerates temperatures from -30°C (cold winter cabs) to 70°C (hot summer cabins) without warping. The internal circuit board is coated with a conformal epoxy layer (0.1mm thickness) that protects against dust and moisture, meeting IP54 ingress protection standards. A vibration-damping foam pad is integrated between the casing and circuit board, reducing vibration transfer by 60%—preventing solder joint fatigue (a common cause of instrument failure) during long-haul trips. Unlike fragile consumer-grade instruments that fail within 2–3 years, this heavy-duty design maintains functionality for 8+ years of daily use, even in rough driving conditions
Plug-and-Play Installation & Self-Diagnostic Function
Designed for hassle-free replacement and maintenance, the instrument assembly simplifies installation and troubleshooting. It includes all necessary hardware: 4 M4×10mm self-tapping screws, a foam gasket (for vibration damping), and a user manual with installation steps. Installation takes 20–25 minutes: remove the old instrument cluster by unscrewing the dashboard trim, disconnect the 16-pin connector, align the new assembly with the cavity, secure the screws (torque to 5 N·m), and plug in the connector. The assembly features a self-diagnostic function—when powered on, it runs a 10-second check of all sensors and indicators, displaying error codes (if any) on the LCD screen for quick troubleshooting. This eliminates the need for specialized diagnostic tools, reducing maintenance time for fleet technicians. Each unit undergoes electrical performance testing, vibration testing (10–2,000 Hz for 2 hours), and temperature cycling testing, backed by a 24-month warranty against defects (e.g., screen failure, connector issues, gauge inaccuracy)
